Abstract
Symbiogenesis presents the biologist with very different explanatory issues compared to the lineal and selectionist view of evolution based on individual entities, whether genes, organisms or species. A key question is how the co-existence of two or more partners in close association during a given generation can ultimately be stabilized enough to be transmitted to the next, how the ensuing complexity is maintained and how this arrangement impacts the reproductive fitness of the collective over evolutionary time. In this chapter, we highlight some observations gleaned from the microbial world that could shed light on this problem if viewed within the framework of constructive neutral evolution.
期刊介绍：
Results and Problems in Cell Differentiation is an up-to-date book series that presents and explores selected questions of cell and developmental biology. Each volume focuses on a single, well-defined topic. Reviews address basic questions and phenomena, but also provide concise information on the most recent advances. Together, the volumes provide a valuable overview of this exciting and dynamically expanding field.
